PositionableStream>>upToAnyOf: is just like #upTo: but allows for a collection of elements to be matched against. Very useful when there is a potential set of matches ahead, for example when dealing with a mixture of cr and lfs in files, such as in: [stream atEnd] whileFalse:[ (stream upToAnyOf: String crlf) ifNotEmpty:[:line| "etc"]. ].
